Frackquakes: Public Opposition Builds As Property Rights Are Endangered in Texas

By Sharon Wilson and Alan Septoff

The earthquakes you may have heard about—the 30 tremblers that have struck north central Texas since Nov. 1 and have damaged many homes. The quakes are most likely being caused by underground disposal wells used to get rid of wastewater generated during fracking operations. “Frackquakes,” some are calling them.

The quakes you probably haven’t heard about are political. They’re caused in part by the frackquakes, and in part by other environmental, social and public health impacts of fracking-enabled oil and gas development. And they seem to be changing Texans’ opinions about fracking.

The oil and gas boom sweeping through the U.S. is occurring because horizontal hydraulic fracturing makes it possible to extract previously inaccessible oil and gas locked up inside the pores of shale rock thousands of feet underground.

How?

Well, by drilling a well down to the shale deposit; taking a right turn to horizontally extend the well for thousands more feet through the shale layer, and then injecting millions of gallons—two to eight millions gallons, depending upon the area—of water laced with tens of thousands of gallons of toxics at such high pressure that the shale rock breaks (fractures). The water and toxics (called flowback fluid) are then withdrawn back up the well, and the released oil or gas follows.

The oil and gas is cleaned and piped and sold. But what of the toxics-laced flowback fluid and other (briny, and sometimes radioactive) water produced by the well? 

Although some of it is reused, the vast majority of it must be disposed of. The disposal of fracking wastewater (flowback plus produced water) is what causes fracking earthquakes.

Because of the chemicals in fracking wastewater, it cannot be treated at an ordinary sewage wastewater treatment plant. Instead, it is injected in another well deep underground. It has long been known that this type of wastewater injection deep underground can lead to earthquakes when it occurs near a fault .

So it is no surprise that as fracking has become near universal—more than 90 percent of all new oil and gas wells are fracked—that the number of fracking wastewater injection wells and associated earthquakes has soared as well.

Especially damning is that places that are historically seismically inactive, like Oklahoma, Texas and Arkansas, have seen earthquake swarms after fracking wastewater injection wells began in earnest.

The U.S. Environmental Protection Agency (EPA) has delegated oversight of these fracking wastewater injection wells to the states. Unfortunately, despite the increasingly apparent threat posed by fracking-related earthquakes, many states are actively ignoring the issue. Nine months after a National Academy of Sciences panel said oil and gas regulators should take steps to prevent man-made earthquakes, officials in key states are ignoring quake potential as they rewrite their drilling rules.

Unfortunately, the damages from frackquakes can be considerable. Originally thought to be minor, new research is showing they can be large. A 5.7 magnitude frackquake near Prague, OK, in 2011 damaged 14 homes and other structures in the area. Particularly in parts of the country where earthquakes were previously uncommon and infrastructure was not built to withstand seismic activity, even smaller earthquakes can cause significant, expensive and dangerous damage.

This is turning the frackquake issue into a property rights issue. Because homeowners (and municipalities) must pay for the damages to homes and public infrastructure caused by these quakes. When asked what should be done about the quakes, Oklahoma government recommended homeowners buy earthquake insurance policies.

Communities Have Had Enough, Even in Texas

In oil crazy Texas, in years past, any evidence supporting the need for caution while drilling would have been ignored by affected communities. But no longer.

Earlier this month, almost 1,000 concerned citizens packed a public meeting about frackquakes near Azle/Reno, TX. When the state regulator holding the meeting announced a “study” of the issue but refused to answer questions, there was an uproar. In response, on the spur of the moment, outraged community members rented a bus to make the four-hour trip to the state capital to demand action from the full Texas Railroad Commission (which oversees oil and gas drilling in the state). Here’s a sampling of comments to the commission:

“In other states where fracking wastewater injection wells have been shut down, earthquakes disappear. This isn’t rocket science. Common sense tells you that fracking waste disposal is playing a big role in this. Don’t make us guinea pigs while you study." — Reno Mayor Lynda Stokes

“This is a property rights issue, pure and simple. The most profitable industry in the country is damaging our homes. And the Railroad Commission is not only allowing it, they’re forcing homeowners to pay the damages.” — Reno homeowner Barbara Brown

Coupled with a de facto moratorium on fracking that the city of Dallas passed late last year, we are seeing a public opinion sea change regarding fracking in the Lone Star state.

These are not isolated incidents. Across the country, opposition to irresponsible oil and gas development is building to a crescendo:

But in some ways, Texas is more important because the state has always been the heart of the U.S. oil industry, embracing oil and gas development from its earliest years, and pioneering fracking in the Barnett Shale. In political terms, Texas is the oil and gas industry’s base.

So when Texans are willing to stand up in open democratic processes—first in Dallas and now in Azle—and say “no” to oil and gas development, it’s a sign that times are a-changin’. If Texans aren’t willing to live with fracking, then it may be impossible for anyone to live in harmony with fracking.

Video Shows Oil Company's Plans to Drill Arctic From Artificial Island

The Liberty Project has posted a video about its proposal to build the nation's first oil production platform in federal waters in the Arctic.

The video was quietly uploaded two months ago and shows Hilcorp Alaska's plan to build an artificial gravel island and undersea pipeline for its offshore drilling project in the Beaufort Sea. Frankly speaking, the five-minute clip—with its all-American voiceover and electric guitar riffs—is something you'd expect from a pickup truck commercial.

Scientists Discover Sea Levels Rose in Sharp Bursts During Last Warming

By Rice University

Scientists from Rice University and Texas A&M University-Corpus Christi's Harte Research Institute for Gulf of Mexico Studies have discovered that Earth's sea level did not rise steadily but rather in sharp, punctuated bursts when the planet's glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.

The findings appeared Wednesday in Nature Communications.

Quitting Coal: New Global Survey Names the Companies, Countries and Cities

More than a quarter of the 1,675 companies that owned or developed coal-fired power capacity since 2010 have entirely left the coal power business, according to new research from CoalSwarm and Greenpeace. This represents nearly 370 large coal-fired power plants—enough to power around six United Kingdoms—and equivalent to nearly half a trillion dollars in assets retired or not developed.

While many generating companies go through this rapid makeover, the research also shows that a total of 23 countries, states and cities will have either phased out coal-fired power plants or set a timeline to do so by 2030.

New Evidence Suggests Ancient Egypt Was Brought Down By Volcanoes and Climate Change

Ancient Egypt is often described as an exotic place—pyramids, hieroglyphics, lavishly worshipped kings and queens.

But in many ways, it has a lot of parallels to modern life. It was an economically diverse, culturally vibrant and unequal place.

The millenniums-old society also struggled with a phenomenon that people today know all too well: climate change. And it may have ultimately led to the civilization's demise, according to a new paper by a team of researchers at Yale University.

The team of researchers studied the tail-end of ancient Egypt during the Ptolemaic dynasty between 305-30 BCE.

Kids Harmed by Portugal Fires Reach Key Crowdfunding Goal for Climate Lawsuit

As Portugal reels from its worst wildfires on record, seven Portuguese children have met an important crowdfunding goal for their major climate lawsuit against 47 European nations.

More than £20,000 ($26,400) was pledged by 589 people, allowing the Global Legal Action Network (GLAN)—the nonprofit coordinating the lawsuit—to identify and compile evidence to present to the European Court of Human Rights in Strasbourg, France. GLAN now has a new stretch target of £100,000.

German Nature Reserves Have Lost More Than 75% of Flying Insects

A new study published Wednesday in the journal PLOS ONE adds more evidence that insect populations around the globe are in perilous decline.

For the study, researchers from Radboud University in the Netherlands, alongside their German and English colleagues, measured the biomass of trapped flying insects at 63 nature preserves in Germany since 1989. They were shocked to discover that the total biomass decreased dramatically over the 27 years of the study, with a seasonal decline of 76 percent and mid-summer decline of 82 percent, when insect numbers tend to peak.

Pushing Toxic Chemicals and Climate Denial: The Dark Money-Funded Independent Women’s Forum

By Stacy Malkan

The Independent Women's Forum is a 501(c)(3) nonprofit that has taken money from tobacco and oil companies, partners with Monsanto, defends toxic chemicals in food and consumer products, denies climate science and argues against laws that would curb the power of corporations.

IWF began in 1991 as an effort to defend now Supreme Court Justice (and former Monsanto attorney) Clarence Thomas as he faced sexual harassment charges. The group now says it seeks to "improve the lives of Americans by increasing the number of women who value free markets and personal liberty."

Toxic Toys? After Nine Years, a Ban on Harmful Chemicals Becomes Official

Phthalates are a particularly harmful type of chemical, used, among a range of other ways, to soften plastic in children's toys and products like pacifiers and teething rings. In response to mounting concern about the serious health impacts of phthalates—most notably, interference with hormone production and reproductive development in young children—Congress voted overwhelmingly in 2008 to outlaw the use of a few phthalates in these products and ordered the Consumer Product Safety Commission (CPSC) to assess the use of other types of the chemical in these products. After much delay, the CPSC voted 3–2 Wednesday to ban five additional types of phthalates in kids' toys and childcare products.
